URLs in titles are useful when you're looking at a printed copy of a page and need to manually re-enter the URL. But given the context that a Monastary page provides, anyone with half a clue should be able to get back to the page in question.
I say, lose the http://perlmonks.org
Comment on Re: http://perlmonks.org: Title, or Trash?
IE (and I assume other browsers) have the ability of putting the URL itself onto the printed page in addition to the page title. So if you're printing something that you think people might want to recall later in their browser, that option should be there... Unless my memory is failing in this respect. It's been a while since I tried printing a web page (though the chick in the office down the hall from me must go through a ream a week with all of the web pages and e-mail she prints).
